Patented June 23, 1908.

To all whom it may concern:

Be it known that I, JOHN URI LLOYD, a citizen of the United States of America, and resident of .Norwood, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Concentrators for which the following is a specification. Y

Y My invention relates to an a paratusby means of which a liquid may be heated at its surface, while the body of the liquid is kept comparatively cool.v Its object is to provide cleaned'readily, and which is sup )lied with a convenient means of ada )tingit for use with varying quantities of the solutions to be treated. This object is attained by the means'described inthe specification and illustrated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view of the concentrating tank, its heating and cooling of the rejackets and in elevatidn of the top the latter celving vessel, the lowerpart 0 being broken away to economize space. Fig.

2 is a horizontal sectional'view taken upon line vo of Fig. 1.

Concentrating tank, A, has its interior free from obstructions .of any character. It is of a cylinder closed at its upper and lower ends by caps, a, a. Near f.- water pipe, G,

or pipe, a which leads to a condenser.(not shown). Into the side of the tank, A, an admission pipe, B, leads, whose opening is controlled by a cock, 6.

Cap, 0/, has a central port, into which a discharge pipe, cock, 0, and its lower end is screw-threaded to receive the interiorly screw-threaded necks of receiving vessels, D, which may be made of varying sizes, but having the same sizedneck, d, for engaging the screw-threaded end of pipe, C. Near the bottom of the tank, A, is an external. jacket, E, whose up er and lower ends, e, e, snu ly contact and are se-' cured to the externfi wallof the tank, A.. Into the bottom of the jacket, E, a steamits upper end is a vap pipe, F, leads, in which is located a regulat- 4 mg cock,.f, and from the top of said jacket eads a steam ipe,'F, controlled by a cock, Into the ottom of the jacket, E, a

enters and from its top exsaid pipes being cong", respectively.

g' and tends a water trolled by cocks, Above the jacket,

which may be I H, throug C, is secured. Pipe, 0, has a I a jacket, H, 1s secured 1 upon the external Walls of the tank, A. A

pipes being controlled by 'centrate to make for instance, an abstract or extract, has been admitted to tank, A, through-pipe, B, to a level reaching above the level at which the bottom of the jacket, H, is secured to the tank, A. The cocks, g and g, in the water pi es, G and G, are 0 ened and cool water tirough the pipe, G, and out through the P p cool Water insaid jacket. The cocks in the steam pipes, F, and F, are closed. Cocks, h h are 0 ened and steam enters the jacket,

h steam pipe, 72,, and leaves the ipe, h, thus kee ing g steam to the jac et, simultaneously with the'admission of cold water to the jacket, E. The result is that the'solution in the tank, A, is heated at its surface, while the bodyof thesolution occupying the tank jacket, H, is kept cool. place from the surface and the vapors pass out through the pipe, a, to the condenser.

same by the steam aeonstant supply 0 ows into the jacket below the level .of the Evaporation takes Initted through the pip e, B. When the solu tion has been concentrated to the degree desired, cock, 0, is openedand the concentrated solution is recelved Into the vessel, D.

of solution at onetime, a vessel, D; of whatever size desired may be secured to the pipe, C, the cock,c, may be kept open, while the heating operation is being,carried on, and as the vapor continues to ass off through the pipe, a fresh su plies o unconcentrated solution may be ad mitted to the pipe, B. Thus, by utilizing diflerent sized vessels D, batches of material, diflering in quantity, may be treated.

Should it be desired to concentrate a cer tain batch of material more, after, it has fallenb'elow the level of the jacket, H, this may be accomplished .by closing the water If it be-desired to treat a larger quantity pipes G, and-G, and opening the steam pipes,

and F, for' jacket, E.

he admission of steam to the. When it' is desired-to clean the tank, A,

the unencumbered interior walls of the tank are very readily cleansed.

Jackets, E and H", are of a construction such that they do not become clogged as do the coils of pipes.

'WhatIclaim is:

1. An apparatus of 'the character described lconsisting of a concentrating tank having its interior unencumbered, a jacket surrounding the tank near its. bottom, a

' second jacket surrounding the tank above the first jacket and a means of admitting a cooling medium to the first 'acket and a heat ing medium to the secon jacket, simultaneously.

In a concentrator for solutions the combottom of the concentrating tan bination ofa concentrating tank, a chamber for'receivmg a cooling medium located near the bottom of the tank, a chamber for receiving a heating medium located above the cooling chamber, means for admittm a cooling medium to the first chamber simu taneously with a heating medium to the second chamber whereby the surface of a solution in the concentrating tank is heated While the body is kept cool, an exit pi e in the and a receiver removably connected with the exit pipe, substantially as described. 5 u
